.materiah such as cotton, wool, and the like,

The objects ofmy invention are to provide a method and apparatus in which" all the steps of the dyeing process, including the washing of the vdyedstock, is carried on automatically, and the dyeingjproperis accomplished without removing the stock 20` from the dyeing bath or'liquor.

My invention is especially applicable to the dyeing of vat colors, suchas direct, sulfur, acld and chrome colors, and other colors which are liable to b eoxidized by being frequently brought into contact with the air while being'subjected to the dyeing liquor. v

With lthese and other objects in View, my invention consists of the method hereinafter described .and claimed, and the combination and arrangement of parts inthe' apparatus hereinafter described, illustrated in the aocompanying drawings and specifically pointed out inthe appended claims.

l In the drawings, Figure-1 is a-view partly in vertical section and pltrtly in elevation of my improved apparayns. Fig. 2 is a' transverse vertical section-fl on the line 2 2 of Fig. 1. Fig. 3 is a perspective view of a container for holding the stock. Fig. 4 is 'a view vof a detail.

"'In carrying out this improved method, lV make. use of a series of vatsor tanks, 1, 2 and 3, which may be made of wood or metal as desired. The vat 1 contains the dye liquor. Its depth may be made much greater than its width,- in order`- to provide a comparatively small surface -exposed to the air vfor a given amount of the liquor.

The 'vats 2 and 3 are provided -with the washing liquid. 'Ordinarily only two are used, but it is obvious that as many may4 be used as it is thought expedient or desirable to use. These vats are arranged in successive relation to eachother, with their top portions on a level with each other.v

Brackets or shelves are erected at the top of the side 5 of the vat or tank 1 and the side 6 of the vat or tank 3. These brackets or shelves consist of supporting portions 7 and arms 8, which straddle the sides of the Vats or tanks and are attached to the same by means of bolts 9 and nuts 10.

The holder or carrier 15 is adapted to carry the loose material to be dyed. This holder is in the form of a closed receptacle,

.which may be cylindrical in form, as shown,

ortion16 and The'side portion 16` is proand is'composed of the side vthe ends 17.

`vided withA a closure -which may comprise the doors 18, hinged as at 19, and furnished wit-h suitable meansv for holdingfthe same closed, as the eye 2O and the hook 21. The side portion l'may` also be provided with the perforations 22, to permit the' dyeing and `washing liquors to pass through the' same and permeate the stock. It is obvious that similar perforations may be made 4in the ends 17, if desired.l For the purpose of agitating the mass of stock, the inside of the walls ofthe receptacle 15 is provided with the pins our teeth 23, which may be curved as shown. The -endsof the receptacle 15 have the trunnions 24 projecting outwardly from their central portions, and the ratchet wheels. 25 `arranged coneentrically with the same, for a vpurpose hereinafter disclosed. These means consist of a pair of parallel endless chains 30 and '31, between which the receptacle 15 is mounted. A ,pair of'sprocket wheels 32, mounted on ,the shaft 33, are suitably mounted to rotate inthe vat 1. The shaft 33 may -be jo'urnaled in the ends34 of the vat 1, vas shown, or any other means may be used for thepurpose. The wheels 35 and 36 vare similarly arranged in the vats or tanks 2 and 3, respectively.` Between the tanks and -above the same are also arranged the similar Wheels 37 and 38'. The

Wheels 39 and 40 are suitabl mounted to ro- 4tateabove the vtanks 1 an 3, respectively.

'The ychains 3'0 and 31 pass alternately under and over the Wheels 32, 37 35, 38 and 36, and over the Wheels 39 and 40. Any suitable means for appl in motive power to the carrier "may be used'.7 n this instance there is shown a belt.41 and a pulley 42' attached to the shaft 43, uponv which are mounted the Wheels 39. I

In practicing my improved m'ethod, I

first place the raw material inthe receptacle 15. This receptacle is then placed on'the brackets or shelves 7. 'Certainof thelinks in the chains and Share provided with the eyes 50. The trunnions 24 of the receptacle 15 are inserted in opposite eyes and the receptacle is thereby supported upon the car- The end Walls 34 of the vats aref rorier,

pins are so arranged that the teeth of' they ratchet Wheels 25 strike the same as the.

4receptacle 15 is carried along on the car in said receptacles than theslower rotation and consequently milder agitation formerly employed.

The speed of the carrier is.so regulated that it may be driven continuously, and at the same time the receptacle may be left asumcient time in the -dye`liquor and the washing baths. After the receptacle; has .passed through the tank 3,' it is removed from the carrier, and in this connection`the shelves 7. may be ,used to supportthe same temporarily. It has been found in practice thatl good results are obtained by having the v depth of the tank 1 of such a size that it will take about a half hou-r for the receptacle to pass through the same, and the depths of' the other tanks are also arranged sothat .it

" will take about the same time for the recepf 'tacle to ass through the washingbath, the

link to be used in thechains 30 and 31. This link -is provided with the eye 52., which is composed of two independent portions and 54. The portion 54 has a dovetailed,

connection, as shown at 5 5, with the por# tion 5 3. This portion 54 may therefore .be .1

tacle,a.series of dyeing and was 'lng tanks,

separated from .the portion 53 by a 'sliding movement. In practice the portion 54 is removed, the trunnion 24 is then inserted 1n the' eyes, and the portion 54 is replaced. In ',using'this form 4of eye it Would therefore not be necessary to spring the chains 30 and 31 apart.

In my method it'will be noted that 4the l material, is com letely treated vvfithl the dye liquor Without eing exposed` to the action of the air. It is also at the same time agitated so that some portions of the material may not be exposed to a greater extent than others to the action of the dye liquor.-

In practice I lill the vat lywlththe dye liquor, 'and as the. same "gets weaker I re-4 plenish it from'time to time with fresh dye to keep-it at 'a uniform standard.V I also may furnish the vats with steam 4pipes and heat the-li uids therein to maintain the temperature o the same at any desired degree. i The liquids in the washing'vatsare drawn od, as they become contaminated withthe dye liquor,'a`nd the vats 2 and 3 are filled with a fresh supply of the Washing-liquid.

The above described form: is the preferred form of myapparatus, but it is' obvious v that many changes may be' made ,therein v Without departing from the spirit and scope of. my invention.

Having now fullv described my invention,

what I claim and esire to secure by Letters Patent of the United States is:

' 1. In an apparatus for dyeing, the combination of a plurality of dyeing and washing tanks, a carrier therein, v'receptacles rotativelymounted on said carrier, wheels on said receptacles, and means for engaging said Wheels to rotate said receptacles at a relatively greater frequency in said Washing tanks.
